Title: Improvements relating to the transmission of electric pulses
IPC: H03K3/543
Filed: 1949-06-10
Abstract: 657,947. Impedance networks. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 10, 1949, No. 15541. Convention date, June 24, 1948. [Class 40 (viii)] An electrical network for transmitting pulses from a source 2 to a load 9 of variable impedance comprises a transmission cable 8 with a delay circuit 10 connected across it, the circuit being short circuited at its remote end, and the characteristic impedance of the circuit and its delay time are such that its impedance during the major part of each pulse is high relative to the characteristic impedance of the cable 8 and is low for a period thereafter. This tends to damp out undesirable oscillations following a pulse. A resistor 11 may be added so that when the impedance of the delay circuit 10 is low the cable termination is matched. A further delay circuit 12 open circuited at its remote end may also be provided adjusted to damp out oscillations at the commencement of the pulse.

Title: Improvements in or relating to anti-friction bearing assemblies
IPC: F16C19/54
Filed: 1947-06-12
Abstract: 624,210. Bearings. BRISTOL AEROPLANE CO., Ltd., and ROBINSON, S. June 12, 1947, No. 15570. [Class 12 (i)] In a bearing assembly of the kind in which a pair of thrust bearings 16, 17 are mounted on a common shaft 12, means are provided for equalizirig the thrust taken by each bearing. The inner races are clamped between a shoulder 20 the shaft 12 and a sleeve 21 and they are separated by a ring 19. The outer races are mounted within a sleeve 24 which is mounted in a circular housing 25 carried by a fixed housing 18. The housing 25 has an outwardly-directed flange 26 at one end engaging the fixed housing 18 and an inwardly-directed flange 27 at the other end. The sleeve 24 has an inwardly-directed flange 30 having a width less than that of ring 19. The outer race of bearing 16 is engaged on one side by flange 30 and on the other by a circlip 29 in sleeve 24. A plurality of steel balls 35 are disposed within a trough formed by the flange 27 of the housing 25 and the chamfered surfaces 32, 33 of sleeve 24 and the outer race of bearing 17. A circlip 28 in the sleeve 25 prevents axial movement of the sleeve 24 in the opposite direction. In operation, with the axial load of shaft 12 in the direction of the arrow 23, the thrust is transmitted through bearing 16 to sleeve 24 and thence to the outer race of bearing 17 via balls 35. Any clearances in the bearing 17 are thus taken up and the load on the two bearings substantially equalized. In a modification the sleeve 24 is disposed adjacent the inner races of bearings 16, 17. The invention is described with reference to a gas turbine engine.

The valve diaphragm 66 is biased by a spring 77 to close the valve 56 and is subjected through a passage 74 to the vacuum in a chamber 96. The chamber 96 is connected through an orifice 104 and a passage 82 to the vacuum downstream of the carburetter throttle valve 26 and through a valve controlled opening 88 to the atmosphere. The valve 100 controlling the opening 88 is operated by a diaphragm 96 subject to the vacuum in passage 82 in chamber 94 and biased to close by a spring 102. Below a predetermined vacuum, e.g. in Hg, the valve 100 is closed and manifold vacuum acts on the diaphragm 66. Above the predetermined vacuum the valve 100 is open and the vacuum applied to the diaphragm 66 varies in inverse proportion to increases in manifold vacuum. The valve 56 is closed under engine idling and wide open throttle conditions.

Abstract: 1,139,426. Chipping frozen meat. W. H. TSCHANTZ. 12 April, 1966, No. 15824/66. Heading A4C. Frozen or semi-frozen blocks of meat are cut into chips by passing a generally laterally extending knife across the end of a block of meat and simultaneously forcing the cut slice against laterally spaced knives extending generally along the path of travel of the first knife and preferably moved simultaneously therewith while being maintained spaced therefrom to further cut the longitudinal meat chip into a series of laterally adjacent chips. In the embodiment shown the lateral knife 43 is mounted at an angle not more than 90 degrees on a knife plate 36 also carrying the longitudinal knives 44 and reciprocated by means 32 connected to a motor in chamber 22. A feed hopper 23 for the meat block is mounted on a lid 69 (shown here in the hinged up position) in such a way that the block is maintained at an acute angle to the cutting stroke of knife 36. A spring 68 urges the meat against wall 67 which terminates in an edge 70 spaced closely above the cutting edge of blade 43. The cut chips fall through the knives 44 and are collected below the apparatus. The cutting edge of knife blade 43 is preferably upwardly raked ((51), (52), (53) in Fig. 5, not shown).

Title: Process for applying rubber and obtaining the latter in a spongy state on fabrics and other materials
IPC: B05D7/12
Filed: 1933-06-02
Abstract: A layer of spongy rubber is formed on one or both sides of a flexible backing such as fabric, carpets, cardboard, paper and leather by calendering thereon without the use of solvents a rubber mix which is vulcanizable at a temperature between 70 and 140 DEG  C. and contains swelling agents capable of forming gaseous products between these limits of temperature so that swelling occurs just before vulcanization, and thereafter vulcanizing by hot air.  The rubber mix contains plasticizers such as palm oil, pine oil and paraffin, fillers and colouring materials such as zinc oxide, baryta and titanium white, sulphur and accelerators such as tetramethyl thiuram mono- or bisulphide in addition to swelling agents such as bicarbonate of ammonia or soda, ethyl alcohol and aqueous ammonia.  A prior coating of adhesive may be applied before the rubber coating which may be talced after application.  More than one rubber layer may be applied and two coated fabrics may be superposed and coated on their external surfaces.  Vulcanization is effected in hot air ovens in which the fabric falls in folds between the rollers on which it is suspended.
